This level was fun, but there were some sections at the end that you should change.
The spike pictured here made me very impatient because most times the turn block bridge expanded the spike did too. Also nitpick: there's a bit of blue color in the log.
This spike is punishing. I would change the turn block bridge to an horizontal and vertical variant.
Please raise the time limit.
those and this should be good.
Also a suggestion: you could use the gold Bowser statues more in the level, I only saw them at the end.
Oh, and sorry for the feedback delay, I had few problems with my PC which are fixed now.
